SHE SHOT TO fame in the third series of Big Brother back in 2002, but former GMTV star Alison Hammond is setting her sights on a new challenge.

The TV presenter is confirmed as the third celebrity taking part in the new series of Strictly Come Dancing.

The bubbly star announced the news on ITV’s This Morning earlier today, much to the excitement of the presenters.

She said: “I am absolutely overjoyed to be joining the Strictly team. I am ready to immerse myself in glitter and hard work, with a dash of fun along the way!”

Alison spoke to Eamonn Holmes and Ruth Langsford about her new, exciting news. She said: "I haven’t got a partner - I don’t know who will take me on!

"I’m so unfit! I’m not gonna lie, I can’t believe I’m doing this show. I’ve known about two months and I’ve been telling everyone, including you [pointing to Ruth]!”

"I’m going to take it really seriously. I am gonna have fun, but this is going to be a great opportunity…. I can’t do heels, that’s the problem. I just want to use the men’s shoes!"

She added: “And I hope the costumes are better than this [pointing to some sequins she was wearing].”

Alison made her name as a contestant on the third series of ‘Big Brother’ back in 2002 - but before that she tried her hand at being a child actress, holiday rep and cinema usherette.

The outspoken star is now best known as This Morning’s showbiz reporter and has interviewed the world’s biggest stars including Hugh Jackman, Will Smith, George Clooney and Daniel Craig.

Birmingham born Alison has also appeared on a number of other high profile television shows during her career including All Star Family Fortunes, Celebrity Coach Trip and the 2010 series of I’m A Celebrity Get Me Out of Here.

After months of denying speculation, earlier this week Judy Murray was confirmed as the second celebrity for this year's Strictly Come Dancing.

The tennis coach - who is the mother of tennis champ Andy Murray - will join The Saturday's star Frankie Bridge for this year's reality dance show.

The announcement came this morning via the official Strictly Twitter channel, alongside a snap of the star in front of the famous red velvet curtain.

Judy had recently denied speculation that she would be joining the show, admitting that her son, Andy, had made up her mind by telling her that she couldn't dance.

Speaking earlier this year, she said: ""It was on the front page of the papers during Wimbledon and Andy asked me about it.

"I said 'no' and he said 'thank God for that, you would be absolutely terrible' which I would. I think it's just a rumour so no, definitely not."

However, after the BBC confirmed the news earlier this week, Judy said: "“I’m a huge Strictly Come Dancing fan but a total armchair dancer.

"It’s going to be a big challenge for me and for whoever has to dance with me but I absolutely can’t wait to get started!”

The first star revealed as part of the SCD line-up was The Saturdays singer Frankie Bridge, nee Sandford.

The pop star, who said she is "a huge fan" of the hit ballroom show, married former England footballer Wayne last month.

She said: "I've always wanted to be a part of the show - it looks like so much fun and the costumes are just gorgeous.

"Like so many little girls, I used to take dance lessons when I was in primary school and I really love dancing but this is going to be so different from anything I have done with The Saturdays. I just can't wait to get started."

The new series will be the first one without veteran host Sir Bruce Forsyth, with Tess Daly and Claudia Winkleman sharing the presenting job.
